Sound insulation-Aluminum foam panel

Aluminum foam panel, as a new concept metal material, is foamed in sponge shape after melting aluminum ingot with various chemical ingredients and has many pore cell inner structures. It is a cellular structure consisting of solid aluminum which contains a large volume fraction of  gas-filled pores. The pores can be sealed ( closed cell AFP, as we called), or they can be formed as an interconnected network( open cell AFP). They are not only acoustic materials but also beautiful decorative materials( we can paint colors on the panels).

Open Cell Aluminum Foam Panel
Aluminum foam (open cell) shows its advantages primarily in combination with existing constructions. The combination of attributes like high stiffness at low weight and energy absorption qualifies Al-Foam for lightweight components with specific requirements.Open cell AFP is sound absorbing, ventilated, fireproof, ultralight, 100%eco-friendly & recyclable, etc.

Closed Cell Aluminum Foam Panel
For the production of foamed aluminum, AL powder is mixed with a product releasing gas at higher temperature and then compacted, this foaming agent is placed into a mold form and heated up until the agent starts to foam. Immediately thereafter the mold is taken out of the furnace and cooled off, so the aluminum foam part is frozen in shape. The outcome of this process is a closed cell aluminum foam showing a thin casting skin on the surface。
Closed cell AFP is soundproof, fireproof, ultralight, 100%eco-friendly & recyclable, etc.
